Submission of a manuscript implies： that the work described has not been published before （except in the form of an abstract or as part of a published lecture, review, or thesis）; that it is not under consideration for publication elsewhere; that its publication has been approved by all co-authors, if any, as well as -- tacitly or explicitly -- by the responsible authorities at the institution where the work was carried out.
